How do you find the average rate of change of #s(t) = t^3 + t# over the interval [2,4]? Calculus Derivatives Average Rate of Change Over an Interval 1 Answer Mia Oct 10, 2016 #29# Explanation: Average rate: #color(blue)((s(4)-s(2))/(4-2))# #s(4)=4^3+4=64+4=68# #s(2)=2^3+2=8+2=10# #color(blue)((s(4)-s(2))/(4-2))# #=(68-10)/2# #=29# Answer link Related questions How do you find the average rate of change of a function from graph?
